Title: Two-laser optical head
Inventor: NAKAMURA SHIGERU
IPC: G11B7/1356
Filed: 1987-06-22
Abstract: PURPOSE:To simplify the constitution of signal detecting optical system and to make a device small-sized and light-weight by turning a package, on which two semiconductor laser chips are mounted and positioning two spots to the same track. CONSTITUTION:Laser beams 2a and 2b emitted from semiconductor laser chips 1a and 1b mounted on a laser package 1 pass a collimator lens 3, a half- wavelength plate 23, and a beam splitter 4 to form two spots 38 and 39 on a magneto-optical film 10 of a magneto-optical disk 11 by a stop lens 9. Reflected beams 13a and 13b are reflected on the splitter 4, and the beam 13a is reflected on a wavelength separating filter 14 and passes a prism 6 and is made incident on a divided type photodetector 8 to reproduce information required for recording. Meanwhile, the beam 13b passes the filter 14 to not only reproduce recording information but also detect the out-of-focus state by an optical detector 20. The package 1 is turned around the optical axis of the lens 9 in this constitution to position two spots 38 and 39 to the same track, and thus, the constitution is simplified to make the device small-sized and light-weight.

Title: Image processor
Inventor: MIURA YUJI
IPC: H04N1/387
Filed: 1994-07-05
Abstract: PURPOSE:To correct an image area of image data without changing the image quality of the image data. CONSTITUTION:The image processor obtains relative position information quantizing image data stored in an real image area generated in a RAM 52 with respect to a routine size area of itself by a CPU 50 when image data are generated and stores image information resulting from adding the obtained relative position relation information as an position attribute to the image data to a hard disk drive(HDD) 61 via an HDC (hard disk controller) 60. Thus, the other equipment or system receiving the image information corrects properly the image area of the image data based on the position attribute.

Title: Production of optical fiber base material
Inventor: OSONO KAZUMASA
IPC: C03B37/014
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an optical fiber base material, enabling to obtain the optical fiber base material free from air bubbles in a process for sintering a large and externally adhered soot base material. SOLUTION: Before a porous soot base material 4 is processed into transparent glass, the porous soot base material 4 is subjected to a vacuum treatment in a closed vessel 13 to remove air from the porous soot base material 4. A pressure treatment comprising filling an inactive gas used for converting the soot base material into the transparent glass in the closed chamber 4 and subsequently pressuring the filled gas enables to replace air bubbles with the inactive gas, thereby inhibiting the invasion of the air into the porous soot base material 4 and preventing the generation of air bubbles on a sintering treatment. Thus, the transparent optical fiber base material is obtained.

Title: Optical fiber fixing device
Inventor: KUSUMOTO SHIGEHIRO
IPC: G02B6/00
Filed: 1988-06-22
Abstract: PURPOSE:To provide the optical fiber fixing device which can decrease the misregistration of optical fibers by forming an optical fiber fixing part of a material which has an insulating characteristic or hardly conducts heat and constituting an exothermic part of a heating resistor and an insulating layer provided thereon. CONSTITUTION:The fixing part 42 for fixing the optical fibers is formed by using the material which has the insulating characteristic or the material which hardly conducts heat, for example, ceramics and a groove 48 is provided to the rear surface thereof. The exothermic part for supplying heat to the binder material which fixes the optical fibers consists of the heating resistor 44a and the insulating layer 44b and current is supplied to the resistor 44a via lead wires 46a, 46b. Since the current does not flow to the fixing part 42 in this case, the quantity of the current required for the heat generation is decreased. Since the supply of the heat to the binder material and the stop thereof are executed without moving the exothermic part, the generation of the force to be the factor for the misregistration of the optical fibers is prevented.

Title: Transfer sheet peeling device
Inventor: UMEZAWA HIDEO
IPC: G03G15/14
Filed: 1988-06-22
Abstract: PURPOSE:To prevent the increase of operation frequency of a separation claw and the scratch of a photosensitive body by adjusting a voltage impressing a separating charger according to the operation frequency of the peeling claw. CONSTITUTION:When a transfer sheet (a) is fed by resist rollers 13 and 14, a leading edge detecting sensor S1 is turned on the start a timer. When a peeling detecting sensor S0 is not turned on until the time A counts up, the device judges that the transfer sheet (a) is likely to wind itself around a photosensitive drum, and stops the timer A, drives a solenoid SOL to abut the separation claw 9 on the outer periphery of the photosensitive drum 1, and mechanically peels the transfer sheet. Every time the peeling claw 9 is driven, the value of the counter A is incremented by one. When the transfer sheet (a) is electrostatically peeled off by the peeling charger 7 or mechanically peeled off by the peeling claw 9, its leading edge is detected by a transfer sheet transmissive sensor S; moreover, every time the process is performed, the value of a counter B is incremented by one. When the operating frequency of the peeling claw 9 is more than 50% of the number of sheets separated, an applied voltage is boosted.

IPC: B65H83/00
Filed: 1985-07-13
Abstract: PURPOSE:To make it possible to prevent paper sheets from being caught to carry out smooth paper-feed, by forming a window for detecting paper sheets in a paper sheet reversing guide plate on a paper sheet conveyor path, and by applying a transparent plate on the inner surface of the guide plate. CONSTITUTION:In an automatic paper sheet reversing device, the conveying resistance of a paper becomes large in the vicinity of a conveying member 80 since the paper sheets are reversed by 180 deg. in this section. Accordingly, a detector 12 for detecting whether a paper sheet surely passing the above- mentioned section or not, is provided having a photosensor as a reflection type photoelectric switch which detects a light reflecting from the paper sheet P which passes this section, through a window 20A formed in a reversing guide plate 20. However, since there is a great possibility of a paper sheet being caught at its leading end by one edge of the window 20A, causing a jam, a transparent material plate is applied to the guide surface of the guide plate 20 so that the paper sheet P is surely conveyed.
